Title Vibrating tables in the concrete industry: Analysis of noise generation mechanisms for noise reduction at the source
Original title Tables vibrantes utilisées dans l'industrie du béton: analyse des mécanismes de génération du bruit pour une réduction à la source [in French]
Bibliographic information 1st Quarter 1998, No.170, Note No.2071-170-98, p.21-32. Illus. 25 ref.
Abstract European directives require manufacturers of industrial machinery to reduce the noise emitted by their machines to the lowest possible levels, in particular by acting at the noise source level. This requires a proper understanding of the mechanisms responsible for noise in each component of the machine. This understanding makes it possible to act directly at the noise source level, and to estimate improvements likely to be achieved. Vibrating tables which are widely used in the cement industry constitute a major source of noise both for the operator and for the surrounding environment. Means of considerably reducing noise emissions at the source are presented in this paper, including reducing workload, limiting shocks, eliminating resonance, and damping the walls from which noise is radiated. The improvements in acoustic performance that can be expected form these different methods are discussed.
